The gender of children is not a constant. It depends on the parental predispositions - mainly on the father's genes but apparently the mother's age can also affect the gender. The details of these influences are not understood well enough to develop an accurate model.
If you make the simplistic but unjustified assumption that both genders are equally likely, the answer is 1/8.
It is 3/8.
2/4
4/6=2/4 n(s)=3 6
2/6 is not accurate. using a theoretical method for equally likely outcomes, there are 2 possible outcomes for each birth: either a boy(B), or a girl (G). For a family of three children, the total number of possibilities (birth orders) is 2*2*2=8 to double check this work, here are the eight possible outcomes:BBB, BBG, BGG, GBB, GBG, GGB, and GGG. You want EXACTLY two girls, this assumes that the other must be a boy. Therefore, the probability that a three child family has 2 girls one boy is P(2 girls)=3/8=0.375
In a family with four children, the probability of having four boys is 1 in 16.
It is 3/8.

50%....maybe you're not cut out for college....
If the family consists of a pair of parents and their offspring, then the probability is very close to 0.
In a family with four children, the probability of having four boys is 1 in 16.
The probability is 2 - 6
The probability of a boy is still 0.5 no matter how many prior children there are.
The probability of exactly 3 girls in a family of 10 children, assuming equal chance of a boy or girl, is 0.1172. This is a binomial distribution.
The probability of a female is approx 0.4831 across the world. If you assume (rather dubious) that the genders of children in a family are independent then the probability is approx 0.3012In a family of 5, the probability of 3 girls and 2 boys is5C3*(0.4831)3*(0.5169)2 = 0.3012
